Caviar is the processed, salted roe of fish (usually sturgeon). “Mexican caviar” is a nickname that has been applied to insect eggs in Mexico that resemble and that eaten similar to caviar. Ahuautli or ahuautle (larvae of syrphid flies) was called “Mexican caviar” by at least 1953. Escamoles (ant larvae) has been called “Mexican caviar” since at least 1989 and most commonly holds the nickname today.

Wikipedia: EscamolesEscamoles are the larvae of ants of the genus Liometopum, harvested from the roots of the agave (tequila) or maguey (mezcal) plant in Mexico. In some forms of Mexican cuisine, escamoles are considered a delicacy and are sometimes referred to as “insect caviar”. They have a cottage cheese like consistency and taste buttery, yet slightly nutty.

On the TV series Burt Wolf’s Travels and Traditions, in the episode The Shrine of the Virgin of Guadalupe, Burt Wolf demonstrated how to eat a taco of escamoles and guacamole. The guacamole is used partly as a condiment and partly to prevent the escamoles from falling out of the taco.

Wikipedia: CaviarCaviar is the processed, salted roe of certain species of fish, most notably the sturgeon (black caviar) and the salmon (red caviar). It is commercially marketed worldwide as a delicacy and is eaten as a garnish or a spread; for example, with hors d’œuvres.

MEX. CAVIAR MAKES MOUNTAIN OUT OF AN ANTHILL
BY JULIE BESONEN

Nobody wants ants in his pants, so it’s prudent for ant egg hunters to get naked before trekking into Central Mexico’s hills when digging for ant colonies. The ants get enraged, naturally, when these giant, nude predators steal their spawn. They swarm and bite to no avail - man beats ant every time in the battle for this local, expensive delicacy known as escamoles, or Mexican caviar.
